A quick connection device for a gas chromatograph

Abstract

The utility model discloses a gas chromatograph's sampling quick coupling device in the field of gas chromatograph, including first joint, second joint, third joint, quick -witted mechanism, fastening mechanism and hose, between first joint with second joint is connected through quick -witted mechanism, the hose is connected between second joint with third joint through fastening mechanism, this gas chromatograph's sampling quick coupling device, through pulling the pull ring, makes the limit circle movement, then the connecting shell is embedded in the shell inside, and the first joint is extruded to the inclined plane of the clamping block, and the clamping block moves, when the connecting shell is embedded in place, rotates the connecting shell, makes the clamping block inlay in the card slot, then loosens the pull ring, thereby makes the clamping block be located in the blocking groove, and the clamping block is positioned, prevents the clamping block from moving, thereby completes the connection, makes the connection more simple and convenient, saves time and labour, accelerates the efficiency of connection, improves the practicality of device, reduces the tediousness of connection.
